In molecular cloning, a __________ is used to insert a fragment of DNA into the host cell.

• plasmid

• DNA fragment

• bacterium

• virus

Organisms that have foreign DNA inserted from a different species are called

• transgenic

• transmutated

• adenoviruses

• haploid

The process where an electric current is used to separate nucleic acids based on size and is used in forensics is called

• gel electrophoresis

• cloning

• transgenic manipulation

• PCR

The process used to make copies of DNA when not much is available and is often used in forensics is called

• gel electrophoresis

• cloning

• PCR

• transgenics

Polymerase Chain Reaction

• Is used to make copies of specific regions of DNA

• Uses a special form of DNA polymerase and primers to copy DNA

• is used in crime scenes and paternity cases to compare DNA samples

• All of the choices are correct

• some of the choices are correct

This cuts DNA molecules at specific locations

• restriction enzymes

• DNA ligase

• polymerase

• ATP

Which technique would most likely be used by forensic scientists?

• gene cloning

• gene therapy

• DNA fingerprinting

• karyotyping

What is the function of gel electrophoresis?

• to separate DNA fragments according to size and charge

• to cut DNA

• to recombine DNA

• to extract DNA

During transformation,

• a prokaryote is changed into a eukaryote.

• a cell takes in DNA from outside the cell.

• plasmids are inserted into a human cell.

• a cell is mutated.

A small circular molecule of DNA found in bacteria cells is called a

• chromosome

• recombinant DNA

• genetic marker

• plasmid
